Please see my response to Matt's sibling comment. If this is truly your own opinion, and you can't see that it is just laughably wrong, then you're definitely working in the right place!
BBEdit was my main html editor from 1994. Back when sites were mostly static files, its multi-file search and replace compatible with regex was how I’d apply site-wide updates, at times pretty extensive ones.
Over the years I have used many editors, I have a weak spot for Atom for code today, but I never stopped running BBEdit.
It comes super handy on a weekly basis and is still the only one that can open huge text files easily.
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.
