Others have already talked to you about the significance of your anecdata and your faintly dismissive tone, but there's something else in your comment that tickled me and that no one's addressed yet:
> 2010-2020 felt like tech dystopia to me. Cellphone incrementalism, walled gardens, adtech, crypto, locked down devices. It was a pale shadow of the excitement of the early web. Personal websites, kids making Flash games, the indie web, p2p, people building stuff being 70% of the internet. For the first time in a long time, I feel extremely hopeful about the future and excited to work with tech again.
Who do you think was responsible for that dystopia? It wasn't those people you mentioned, who built the 70% of the old internet. The enshittification started when the people whose passion in life is to make money caught the scent of money-making potential the internet had.
But then, how did those people actually accomplish the enshittification we're dealing with now? The answer is: with the enthusiastic help of the True Believers. Crypto is the best example. Just recall how many devs were convinced that the blockchain was going to revolutionize everything. And I mean devs. Not snake-oil peddlers in suits, not LinkedIn influencers, none of the usual posse of posers, but people who actually wrote code and were reasonably good at that.
And that's not the only example, just the best one. I've been there myself. Back when OOP, UML, capital-A Agile, CMMi, and MDA (Model Driven Architecture) were the Hot New Thing, I was one of the True Believers, following the trends and proselytizing my colleagues.
Every bit of the dystopia you lament was pushed by the combination of ambitious MBAs and True Believer devs.
And the reason I bring this up is because you're one of those True Believers now. It's easy to fall into that trap. All you need is to have enough good experiences with the Hot New Thing to suppress your critical thinking and believe that this will Make Everything Great Again.
The same kind of people who profited off the tech dystopia you saw are now ushering a new, worse tech dystopia that you're turning a blind eye to. Your belief that this new tech will somehow balance and even counteract what those people did to the internet you loved is not based in facts. It's faith.
