Many possible reasons.

Eg Ryanair operates a completely uniform fleet, 100% 737s, and their current operating model relies on all of their pilots and crew being able to operate whatever aircraft is available. Adding a few airbuses means a split fleet, causing significant logistical and training costs. And their customers are evidently happy to prioritize flight cost over their aversion to the 737max, so why would they switch?

Also, an aircraft being on the market doesn't mean you can actually order one and get it anytime soon. Airbus has like a 10-year backlog for A32x deliveries.

...and just to make sure that any possible aversion is, er, averted, they have renamed their 737 MAX to "737-8200" (and rely on journalists publishing press releases without research to improve its reception: https://www.essexlive.news/news/essex-news/stansted-airport-...).

That was always the model designation though, 737-MAX is just branding. And 8200 is just one of its specific versions.

For example the 737-NG was called 737-600 through 737-900 (different versions)

They did indeed drop the MAX branding and replaced it with the numeric designation because MAX got a bad name after their screwup. But they didn't invent the new name, it was always there.

I don't understand why anyone would fly Ryanair ;)

Sometimes there is no choice, e.g. Prague-Malaga. The alternative routes that go on sane airlines require changing planes. Otherwise I agree with the sentiment :)
