Given the cost of the infrastructure needed to run those large language models, it's very likely that Microsoft is still operating copilot at a loss. I don't see an issue with it being a paid service as it is a costly service to provide.

What I pity however is that there's no free tier for hobbyists as paying a 10 usd monthly subscription wont make sense when you only code occasionally. For professionals using it everyday, 10 usd / month is inconsequential.

I don't think that would have costed them much more to offer a free allowance to cover say an average coding session of 8 hours per month.
