I suspect that a lot of the people in the comments against the freedom truckers and the event are either bots, "journalists", Canadian Government employees or political operatives all paid for by the Liberal party of Canada. A lot of the Liberal voters in Canada are simply people who have no idea what is going on. Viva Frei ran for the PPC in a Montreal riding and when he was campaigning on the streets, there were a lot of Liberal voters who thought he might be a Liberal candidate because they didn't even seem to know the official colours of the Liberal party of Canada. There are also people who religiously follow and believe the media too so would hate the freedom truckers, however I don't see those people bothering to go on twitter to post comments.

Note that for the Oakville Canadian tire rally, there also seemed to be a flood of comments against that party especially from twitter links pointed to by mainstream media articles. However, it was telling that exactly 0 of the people commenting showed up to that event to counter-protest it. That is why I tend to think that a lot of these outraged responses are manufactured to gas-light us into thinking that there are a lot of Canadians that are strongly opposed to any anti-trudeau movement. The truth is, while a lot of Canadians do blindly follow and believe the media, most of them don't actually care about and are not offended by these anti-trudeau parties which is counter to what the people in charge of Canada want us to believe.
