That ease of access comes at a price, yes. But that price is not justification for everyone to be as selfish as they want. That price is you may meet people you don't like, you may get people who aren't skilled, etc. That price is not "Other people have the right to impose their playstyle onto you and 2 others and you have no right to say anything".
You don't see this sort of toxic thinking on JP servers from what I've heard. People there generally try to contribute, even if they have to do some things they don't like with their job, for the good of the group they're spending their time with. They don't think "me me me, forget the group"
If you want to sabotage your group, maybe you should be the one to try and get a group who likes the idea on PF, because I guarantee you: More people will prefer a bard doing their best and using WM, or at least trying to use it correctly, over one who refuses to because they don't like it and sabotages the group.
If you're going into a dungeon thinking, "I don't like this skill so I'm not using it", you're in the wrong. Think for a moment how that would turn out if every player did this with every job. Please don't advocate intentional group sabotage, and please don't try to advocate censorship of people who have problems with this.
