There will be no a lot of solution about that until those companies (apple and google) will unban crypto. Both companies are giving non sense reason for that. it looks like they are feeling worry if crypt will grow even more.
if that is for android user and there was a lot of solution for that but not for apple. US customer can only access the dapps from their desktop.
It's not clear what's the real reason behind google and apple to make that policy.
Metamask's case is the best example about that.
Maybe, some people take advantage of the growth of Blockchain and DApps to deceive others, such as stealing user information, etc. Regarding the fact that Google has stopped all ads related to cryptocurrency, or Youtube removed all videos related to crypto, in my opinion, both almost aim to keep safe for the user.
Such as EtherDelta and IDEX were once well-known decentralized exchanges but have all become fraudsters after their ICOs. Perhaps, that thing made companies like Apple and Google try to eliminate DApps besides to pressure from the government. They worry they can't protect the user when these DApps do the same thing as what EtherDelta or IDEX did. Of course, just my guess.
