This just isn't true. Part 121 operators develop and manage their own maintenance plans. That is done in conjunction with Boeing and the FAA but their maintenance plans may very well deviate from Boeings prescribed service and intervals per their standard maintenance manual.

Look I'm all for the "Fuck Boeing" circlejerk but as someone who actually works QA at an aircraft manufacturer this is likely a whole lot of nothing.

I'd be shocked if you could find a single aircraft of any make in service that didn't have dozens of misdrilled holes.

Without any context this is just fear mongering.

So the general consensus is that these power ratings are a fuckin joke right?

A friend of mine picked a Mars 3 Pro up recently and has really enjoyed it. He was very experienced with FDM printing but this was his first resin printer and I don't believe he's had any issues.

Can't speak for the cleaning/curing station as I believe he made his own.
