Go to this link https://open.sentry.io/ and explain how it is made clear that Sentry isn't actually open source. You can't. No amount of good faith turns "We're Open Source and we don't feel the need to qualify that statement" into "we aren't open source but we'd like to be close to". They are even directly asking in that page for help (for people to volunteer their time). The title of that page is a lie and they make no attempt to clarify it. I can't think of any good faith reason why they wouldn't just write "We're Source Available" since that is a more accurate description of what they are and they've been repeatedly told this. It's obviously less misleading not to over promise when you don't actually know the truth of the matter. The only justifications I can imagine for that title are that they either don't understand that they aren't open source, or that they want to appear open source to attract customers. Given they've had it explained to them repeatedly and even members of their company admit in this thread admit that they aren't open source (but claim they don't say that they are which is a lie) and that the page in question is advertising their product, I can only conclude the latter justification. That they are doing this to move product rather than to inform people.

A charity is an organisation of people can donating money or doing volunteer work to contribute to a cause they see as in the common good. An open source project is an organisation of people donating money or doing volunteer work to contribute to a piece of software for the common good of its users. They are more than a little similar. Even if they aren't, people deserve to know where their work goes if they are doing it for free.
