If I’d got a 85” TV as a gift, should I complain about the fact it has 2 HDMIs instead of 6 I require? Such TVs are usually expensive so I could argue it should have 6 ports but then there’s some kind of compromise design is making.

I’d argue that having 2+ external monitors is not a standard cohort of users, and I’d check support before buying (in fact, numer of HDMI ports is one of the main parameter I check in TV contest). Yes, it doesn’t support that, it’s not a secret though.

Should it support? I, personally don’t care. Some people care. For those who care it’s design flaw, for those who don’t it’s not.
