Eg. they are paying random people to host their models exclusively on MakerWorld (where the CCP tells you what's okay to print; try searching for anything 'Jinping'...). They are obviously pouring enormous amounts of cash into marketing on social media, especially YouTube (a lot of large maker channels became full-on advertisement platforms).
Their expenses are evidently enormous. There is no way they are running sustainable. It's a long con.
So to say you spend significantly less money for a product that will be changed whenever bambu sees fit to whatever extend they see fit.
I regret my bambu purchase a lot. I have to keep up with all the ways bambu wants to lock in my hardware and take it basically away from me.
