Now, for an actual sane take, unless we do the actual marketing work in order to gather interest from people, no, not even close to everyone will switch to Linux, specially considering Microsoft has literal millions of dollars to spend in marketing and will likely spin this in a way that non-techy people specially will buy in due to not knowing any choice.

This is a PSA begging people to contribute to their favorite distros not (only) with code but with marketing. Social media posts, videos, word of mouth recommendations, advocacy, events, etc. If your distro doesn't have a marketing team, create one, as most projects should already have done two decades ago. If your distro has one (like we do in Fedora), join it. There'll likely be something you can help with.
