I get the appeal of Bambu printers, I've been tempted myself to get one... but the thing that keeps me away is that they are closed source and I don't want a world with closed source 3D printers because when the company goes evil - and they all eventually do - I don't want to be held hostage. I've fallen in that trap before and don't want to again.
Don't give them backlash, instead stop using their printers. Release your models under a license that requires the printer that prints it to be open source. Let friends and colleagues know the dangers of supporting such a company.
