I just find these comments to be so strange. You can look at all of the articles in that blog to see all of the feature improvements that have launched in Docs over the past 2 years. It's a lot of stuff.
Maybe they're not features that matter to you, some are available only to paid customers as opposed to free tier, or maybe you just haven't bothered to even notice. But they're there.
It's nothing about Google specifically -- I see people make these comments about so much software, where they assume a project is or has been dead, just because they can't even be bothered to look at the changelog. It baffles me.
It's like, unless it's a radical total UX overhaul, people don't notice the work developers are putting in on actual features. And if it is a radical total UX overhaul, people complain about the change because they assume it's superficial rather than actual features.
