It's kinda spamming someone's wallet - so it's a bad thing imo. Though everyone has their own point of view.
We really don't want marketers to spam our email then why should we allow the marketers to spam our wallet as an example? Both marketers of the two kinds haven't taken our permission.
Most of the times those airdropped token stays in your wallet because it has ZERO value.
If you want to clean your wallet then you need money, so we will be spending ETHs to clean ZERO value. If those tokens have value then scenario could be different.
An example: I really don't know anything about these tokens but it's in my wallet and made my wallet congested...

There is a lot of projects who never airdropped this way, but those are the successful ones. If anyone has a good project then it will be successful even without the airdrop.
It's like free marketing and free marketing is always spammy.
Not entirely bad, distribution to many people is important to increase the number of users, because if ICO only relies on investors, the number of users will be limited, airdrop will open the opportunity for the project to have more names and links. I think the developer has formulated it well, what is the right airdrop allocation so that it does not have a negative impact on their market
I don't think this a bad strategy but the developers need to think the portion of distribution, if not the amount could hurt the price when its being launched, usually yhe developers choose airdrop to increase the popularity and hopefully could increase the transaction volume, who knows they become attracted to used it for transaction, but airdrop is not too favor for investor because it can caused the price drop severely
