I feel about it the same way as if someone deleted my code comments without first asking me. The comments do have my name on them and I did mean to write what I wrote. I am an adult. Someone else feels like they should delete my comments. This is totally subjective. Can I think for myself for once? If I do not like my old comment, then I will remove it. Others can too. I moved from SO ti PSE because I could talk to humans, not machines. many questions, answers and comments do fit the guidelines technically, but are pretty stupid nonetheless (in my opinion). It is one thing to have a democratic process where the community decides to shut down an answer or a comment with enough votes. It is different when the chosen few decided to delete a bunch of good, highly-upvoted comments, and then leave their own comments in place, basically saying "Commenters - screw yourself. This is my territory. I get to delete all other comments and leave only mine here. This is exactly what you need and why you elected me, I swear.". Do as I say, and not as I do. This is just like in politics. You vote for the whole package. They look great when running for elections, and then they start power-tripping. They also use coercion in the name of greater good.
So, Stack Exchange is a for-profit organization that owns the content. I thought they were hip and not MSFT-like, anti-dictatorship and all. They feel like they can make more money by strict policing, although they sell this under the guise of helping the programmers. Well, I happen to hate a lot of "nerdy talk" that is so common here and is supposed to be cool. I do not go about deleting those answers or comments. I rarely even down-vote them. I just accept this for what it is - most programmers are dorky geeks whether I like it or not. In terms of filtering out the answers and comments - the most useful already float to the top. if you do not like my comments, then do not read them. If they suck, then they will not be up-voted much and will be harder to find. But no, we have got to censor everything in order to protect the innocent.
Whatever happened to freedom? Ah, right, I am on a private property of the Stack Exchange which owns my posts and thoughts, so my freedom is limited by their EULA. Fair enough, I shall vote with my feet then.
PSE is a very subjective forum.
if you feel like responding to my post, do not even try to leave a comment. Instead, visit the http://chat.stackexchange.com/rooms/21 as I have been told, and hope that I will show up there as well.
So, this is how I feel about the forced, unbeknown deletion of comments.
