Airdrops have not given users or testers what they wanted lately. The fact that the market is red has a big impact. The other reason is that Airdrops really give a feeling of saturation in the market because there are L2 projects and testnets everywhere. Since many people are flocking there due to the excess demand, I think the desired profits are not being made, at least not as before.
Too much player and the devs like to screw people up is the main reason.
so many projects also aren't transparent with their eligibility criteria which I presume is intentional so to avoid backlash and also they probably like to pull some string behind scene and don't want people to find out.
right now the airdrop isn't as good as before and arguably we're coming at the late stage of airdrop where most of projects that did TGE have their valuation tanked because there are too many projects already.
so many projects released where the demand slowly fades
