But that's just the "circle of life" no matter what. Things start very simple, and then inevitably get ambitious and try to add new gizmos. Sooner or later you end up with a monster.
Historically FOSS has been far more resistant to this cycle; not all FOSS projects, but many. It's much easier for FOSS projects to just say no, and they can spend years or even decades refining things. In the commercial world you can never say no. Not only that, but you have to constantly add features.
Now that corporate interests dominate in many corners of the FOSS sphere, this benefit of FOSS is diminishing. Which is a shame, because it's a big reason why FOSS was so successful, and why so many old commercial projects collapsed under their own weight, even though they always had more features than their FOSS counterparts and thus theoretically should have only grown their user base.
This is true - but I think the interesting (and understated) part of this argument is Big Tech's influence on the process.
Say I want to fork etcd or build a greenfield alternative - I now have to compete with (or support) the Hivemind's preferences in direction/progress. Who's to say their way is the "best" way?
I think this tension is much greater than it was 10 years ago.
Over and over again.
