The macdonald's filed for bankruptcy in 2019 and was abandoned since then, the ex employees revived it and opened a food bank. The city bought the place and gave it to the people managing the food bank.

People on HN react as if these people forcibly entered the place and violently took the control from a successful hard working business owner.

I see two options:

Either people simply don't understand the situation and side with "hard working business owners" because that's who they identify with. Or they are so disgusted by charity and solidarity (oooo socialism bad) that they prefer a place to be abandoned and useless than serving a greater purpose
