I still hear about them and buy from them, but I buy a lot less because:

1. They were bought by IGN, so they're a for profit group now
2. Changed Choice to offer major AAAs more often instead of being focused on indies
3. They set slider for minimum percent to Humble in bundles to 15% (I used to give about 20-30% to Humble, now I do 15% as a form of minor protest)
4. Bundles often come with coupons for the store instead of just being bundles of games, and the $1 tier is either complete trash or non-existent

And so on. Basically, they've gotten more corporate, so they're less unique vs the competition. In fact, I've picked up more bundles from Fanatical than Humble in the last couple years because I no longer feel a preference for Humble, and now just go where the deals are.

I'm guessing some or all of that is why the sources you follow don't mention it as much. It's still very much a thing though.
