You post a lot and the posts are often very contrarian. This is a discussion forum so people react to your posts and they might not always agree with you.
@Locutus of Bored has just explained this to you in the Misc forum, like I'm doing now.
You are free to post but your posts are not free from criticism. I and others merely disagreed with your opinion here and did so in a civil way. Never attacking you.
Sure, you are allowed to think that. It just has no relation to the actual meaning of the word. They cannot plagiarize because they own the IP and give credit.
