I'm asking just about people born in HK who were just BN(O), weren't British citizens, and had no other citizenship or nationality.
Is this Reddit comment right?

Why didn’t the UK offer them citizenship or give them British Citizenship like Portugal did with Macau?

The UK kind of did. When the handover happened anyone in Hong Kong was offered the right to abode in the UK, which is basically citizenship without the right to vote. If you live in the UK for a while legally it becomes rather easy to get citizenship so it's kind of a formality. Quite a few people took that deal, too. One of my best friends was born in Hong Kong and lives in the UK because of that exact deal.
After the Tiananmen Square massacre in 1989, many people in Hong Kong began to fear for their future post-1997. Emigration was rampant and a brain-drain was beginning to affect the economy of Hong Kong. To stem the drain, people urged the British government to grant full British citizenship to all Hong Kong BDTCs – but this request was never accepted. However, the British did agree to creating the British Nationality Selection Scheme, which granted to a select 50,000 people and their families the ability to obtain full British citizenship without having to fulfill the ordinary requirements, under the British Nationality (Hong Kong) Act, 1990.
