It only matters because they have no competitors, otherwise you'd say the same applies to AWS hosting the origin servers, and the databases of those very startups likely to use Cloudflare.

In the end, if there were true competitors, it probably wouldn't matter much, they would be just one popular service that handed your data like many others

They also have plenty of competitors, the CDN space has more companies than the ISP space so the internet is already more centralized at a much deeper level. This a silly claim by the OP.
