I agree. When I bought my factory (SIM) unlocked Note 10+ (which I loved the hardware but hated the software on) in 2020, I thought I'd be able to unlock the bootloader since it wasn't tied to any specific carrier version of Note 10+. I went back to Pixel (6 Pro) although I hate being without a MicroSD slot - but recent Samsung flagships don't even give that.
I apologize for off-topic.
For the record, at least in the United States, if you buy a carrier-version of any Tab S8 variant, then you can't unlock the bootloader. So, only non-carrier Wi-Fi models in the U.S. can have the bootloader unlocked.
