You can use any filament you want, it works fine on LAN and SD-cards without online account. There was some debate on the fucked up firmware updating thing, but they did backtrack on this, no?

Sure, but your machine is also 3x the price (at least on my country).

That being said, my next printer will also be a prusa, but mostly because it’s a European company. I’m also for Foss 3dp, but I also don’t want to be caught up in misinformation - please enlighten me if there are serious issues actually happening and not just “well Bambu might do so and so in the future”.
