Most people don’t want to use a 3rd party slicer or switch out the screen.

The Bambu studio slicer and screens that come with the printers both work well.

I really doubt they try to restrict filament brands. No one does that.

Their brand nozzles are the same price as 3rd party ones.

And personally I’ve used both and the Bambu brand ones are better. They are also designed to break instead of destroying the entire print head if there is some big obstruction.

Most people don’t want to tinker with their printers constantly to get them to work.

Or install 3rd party firmware.

They just want the printers to work. Bambu just works.

So many hours have I wasted trying to fix hardware problems on my ender 3 v3. Or tweak settings in the slicer that never fixed the issues.

So much time spent on reddit and YouTube, troubleshooting.

The Bambu just works. It always just works.

If I want to tinker with something, I’ll unpack my ender I’ve put away. But I don’t see that happening.

Sounds like you are someone who wants to tinker with the printer. In your case , no, a Bambu probably isn’t the right choice.

But for 90% of people looking to get into 3d printing, bambu is the right choice.

Most people lack mechanical skills or knowledge and get frustrated with sub par printers and don’t stay with the hobby.
Bambu allows more people to get into the hobby. Which means more unique filaments because there is a market for it. More creators. Because there is a market for it.

It’s a win win for everyone.
