I disagree with this one pretty strongly because it's important to consider it in relation to the amount of internet users.
The early web was less corporate largely just due to its small size. If you take into account the number of users I'd argue that the corporate web peaked about 10 - 15 years ago, ever since then there's been a gradual shift towards more diversity. If you grew up in the AOL messenger and Yahoo news era not only was it corporate, but there was one corporation for like, everything. In 2010 you had effectively 1 social network, Facebook. Internet Explorer had a marketshare of 95% at its peak.
Today it's still heavily commercial but that's not the same as corporate. There's a lot of alternatives now, Signal, Telegram, niche decentralized alternatives, direct consumer facing creator focused platforms like substack, patreon, onlyfans etc. Even Amazon to me seems way less central and with more alternatives than it did 5-7 years ago. Netflix has more competitors, as a software developer you have a much healthier open source and linux ecosystem, and so on.
You have to have some pretty heavy rose tinted glasses on if you think creators, devs or endusers had more choice on the internet 20 years ago than they do now.
