WordPress is GPL - the GPL, like all "Open Source" (using OSI's definition) licenses enables commercial use, and that is a subset of one of the FSF's core principles (The freedom to run the program as you wish, for any purpose).
By Matt - no one has claimed it formally but I think there's at least a plausible claim that he has violated part 6 with his attempts at extortion, which requires "You may not impose any further restrictions on the recipients' exercise of the rights granted herein". Especially clearly as it pertains to any existing nominative use's of the WordPress trademarks within the unmodified WordPress code (which trademark law in no way prohibits WPE from using, and Matt demanded were changed).

On WordPress.com, you can pay for hosting plans, some of which give access to plugins and themes, but you also have free hosting without.
Elsewhere, you pay for hosting; there's generally no free option. Then you get plugins and themes included with that.
In the end, to use WordPress with plugins and themes, you pay some amount to the company that hosts it for you.
Disclaimer: I work for Automattic, but the opinions here are my own.
We've invested a ton in products like WordPress Studio, which let you run unlimited local copies of WordPress with however many plugins, themes, etc you want.
Then from 2017 until apparently the last couple months, you had to upgrade past the Free, Personal and Premium plans to the $25/mo Business plan in order to install plugins.
Now it looks like its just your free tier can't do it - I suppose that's fine. 20 years of providing a bastardized simulacra of wordpress was long enough!
All other hosts have always provided full-fledged wordpress with plugin installation with all plans
But, of course you knew all of that and were just trying to misdirect people, yet again. I now fully expect some half-truth pedantic response about a technicality about dates, plan names, or a niche host who also provides a simulacra.
Maybe you think Coca-cola should taste a certain way, and want to sell that to consumers, but without commercial rights to the trademark you can't do that under the Coca-cola brand, you have to call it something else.
It has to do with you calling WP Engine a "hacked up, bastardized simulacra of WordPress" for turning off post revisions, which are an extremely minor part of WordPress (and could be turned back on upon request).
All while - rather than "reserv[ing] custom code at the higher-priced plans" (which is yet another baffling lie) - for the first 12+ years, custom code and plugins (the core of Wordpress and open-source) were completely unavailable[0]. And then for another 8 years it was only available on $25+ plans.
So, I reiterate: WP dot com is/was the most hacked up, bastardized simulacra of WP anywhere.
But, apparently by your logic, when you cheat the IRS via self-dealing and lie to the entire WordPress community about relinquishing control over WP, only to secretly take it back in the same day, that gives you the right to sell RC Cola as Coca Cola - causing endless confusion to newcomers about what Wordpress really is. It was "WordPress with an asterisk" [1] as you yourself recently put it - except there was never any asterisk anywhere, and especially so til 2017.
You're really not good at this Matt. You should get off the internet.
p.s. Lest you claim, like you have so many times when faced with criticism, that I am a paid shill for WP Engine: No one should use either of your services.
