I don't know where your aggressive comments are coming from.
I've been a Webflow partner since 2020, and I still use and love Webflow every day. I just wasn't excited about yesterday, the biggest announcement for me was Tim joining.
I had a look in more detail about Source and I'm excited to test that out, but I don't know what's the reason to pay for that (most likely) when there are open source alternatives that do the same for the most part.
In any case, will need to wait and see.
