Once heretically questioned, why haven't big companies like Google, Amazon or Apple developed any projects with the blockchain, if this the technology is so great?

So far, there are no signs that these companies have ever dealt with the blockchain.

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

There is plenty of interest in the technology and with improvements/modifications and testing being done all the time it will be a matter of time till more companies will start using it.

Blockchain is great for decentralized applications, not so great for what big companies do.
Big companies are centralized and are subject to regulations, they cannot make easy use of decentralized blockchains.
Blockchains are for people and for small companies to embrace. Don't expect big companies to step in and do much with blockchains.

Many companies are still eyeing this technology.
Some already implement it on their products.
All this takes quite a lot of time.

Blockchains are for people and for small companies to embrace. Don't expect big companies to step in and do much with blockchains.

Indeed.  Block chains have a lot of hassle, exactly because they need to be trustless and permissionless and the brilliant idea of Satoshi was a way to solve this almost impossible puzzle: how can we make a common database that can be trusted, if nobody trusts one another and just any wolf can join us in trying to screw up the database ?

Most businesses don't face such problem, so they don't have to live with the cryptographic hassle of a block chain. 
And in as much as different business that don't trust one another, need a common data base, they don't need to open it up to just anyone, and they don't need their untrusted partners to be anonymous.  So there are then easier ways than block chains to do the thing, although you can always call them block chains if you want to hype it.

they have, you don't know about google and microsoft launching their private blockchain? amazon didn't and apple have their own money system with apple pay, but google is building something with the blockchain, just search with google like this https://www.wired.com/2017/03/google-deepminds-untrendy-blockchain-play-make-actually-useful/, google is messing around with deep learning and bitcoin

i think the big company don't want to risk their money to something new technology as government from the big country is not yet accepting bitcoin (or maybe they developed a projects that we don't know). maybe they only watch and learn about blockchain first and make sure they can get profit from blockchain because without the profit, they don't want to start the project.

blockchain is simply a chain of blocks, and blocks are simply raw data. a blockchain is putting this data in a specific structure and then chaining them together, one after another with some additional mechanisms to prevent any tampering with any of the previous data.

now why would these companies want to use this technology?

with that said, this is being used. in fact a lot of financial institutes are looking into this. there even have been talk of non-financial aspects such as a hospital storing patient information on a blockchain.
so there are works being done on this tech, and some of them we know and some we don't.

That's the essence of the difference between a block chain on one hand, and a hash chain, a hash list and a database on the other.

I think its just not interesting enough for the big companies that you mentioned. Like for example, google will not be so interested in this as it is more focused on ads as that is their primary business. The blockchain and ads don't actually mix so much.

Still early days, they will be looking at it behind the scenes and figuring out how to best use the technology.  A quick google on Google shows that they are working on their own version https://qz.com/929833/googles-goog-deepmind-is-using-blockchain-technology-to-handle-nhs-medical-data/

They probably won't announce their plans and their tests with blockchain. Probably experimenting with their own solutions for their problems. This is not something hard and expensive in comparation what theycan et from it. Yes they are preparing something but won't to start a panic, new product will be glorious and shiny with greate marketing support.
