I didn't buy this printer as a tinkering project but to print stuff and at that it really is very good.
There are plenty of other printers that do this. Prusa, Creality, Flashforge, Anycubic. Plenty of slicers available. I don't know why you're pretending Bambu is necessary, or like it's the only option.
Any time I find print files online that are in .bgcode format, I'm like "seriously...".
I usually slice projects myself anyway because I don't use PLA, but it's just kinda lame to post a project online using the only closed source format that only works with one kind of printer.
Plus, there's the whole spontaneous combustion issue...
