Agreed, up to a point. Many film critics have never been directors or actors, and that doesn't detract from their criticisms.

But the OP is releasing this for free, and that helps other people. By crapping on their project with random, unfounded opinions, we discourage them from open sourcing their other code, and that makes the world a worse place. If you don't like an open source project and it's existence isn't doing the world any harm, then just be quiet and move on - or even better, release your own better version.

OP also submitted this link to a discussion site where people don't believe criticism is forbidden or may only be given on the submitter's terms.

Of course criticism is not forbidden - if it was, then I would be flagging these comments for deletion. Instead, I am criticising your comments, and that is also not forbidden nor only allowed on your terms. It works both ways.

You aren't making any criticisms, you're just throwing out a boilerplate demand for people not to harsh anyone's vibe by criticizing anything released open source. (Lest the OP figure out a way to release simple CSS classes in a proprietary format, I guess.) The criticisms aren't particularly "random" or "unfounded", they're on-point: this isn't something that "helps" much, it's just some CSS to make some basic, pointlessly distracting animations.
