Yes, they load up Android with their own versions of apps in an attempt at end-user lock-in to their ecosystem, plus various other, what I consider, unnecessary padding that's not uninstallable. The new life breathed into an older Samsung device by the installation of LineageOS is what I consider the proof of this. Overall it's entirely subjective, however. I prefer minimal base Android so that I can choose which apps are allowed to annoy me with their various reminders to create an account, log in, look at these new features, rate me, etc. Other (less technologically savvy) family members love their Samsung apps and the ecosystem, and just find my setup to be confusing or overly complicated.
