The link GP posted is literally about that, when "Joe's ice cream parlor" is actually the entire city, maybe you should.
Should Google be allowed to forbid criticism of Google on their platforms? I mean, perhaps - but it's hard to argue that there couldn't be consequences from that.
In the 20th century, here's how you could tell the good guys from the bad guys. The bad guys forced you to agree. If there were inconvenient facts or opinions, they were suppressed and the people espousing them were coerced. By contrast, the good guys were open. They let people criticize them, letting their good deeds speak for them. The bad guys destroyed lives just to get their way. Here's the thing: The good guys and the bad guys weren't properly defined by their flags. They weren't confined to particular geographic areas and constrained by borders. The good and bad were defined by the above actions.
So let's apply that to the present day. How does Google behave? Are they the kind of people who would suppress opinions they don't like? Are they the kind of people who would do something intellectually dishonest, like leave out the references? Are they the kind of people who would be the opposite of open, and use superior force to get their way?
Indeed, it's hard to argue that there couldn't be consequences from that. The arc of history is long, and it bends towards justice.
Platform has never meant "open to everyone". You always have the right to shout racist slurs from your soapbox in the public square (at least until a police officer cites you for disturbing the peace or something), but don't expect to do the same in Joe's ice cream parlor and not get thrown out. Consequently, if you go into the KKK headquarters and start preaching equality, they have every legal right to have you kicked out as well
