I'm honestly surprised to see so many "No" answers to this question. From the anti-commercial replies, I think at least some of the No's come from a concentration on the word "markets" rather on the word "competitive". I think the economic definition of a "market" encompasses non-commercial services and products. But maybe I should have found some wording that doesn't make people hit the "I HATE COMPANIES" button so hard.
I also think it's catastrophically bad to think that only computer manufacturers, mobile phone makers, domain registrars, hosting providers, and terrestrial and mobile ISPs should be allowed to get paid for providing Internet services. Many people who spend hundreds or thousands of dollars a year to get access to the Web are reluctant to chip in $20 for their Mastodon server.
