Vim is getting more popular. Not just within vim, but outside vim! Practically every full-featured editor has a vi or vim mode, and when they say vi, usually they also mean vim.
Yeah, the current situation, with no registered trademark for vim the editor, seems to be great for everyone! Vim is popular enough that it's unlikely to be taken. However, someone is currently trying to claim Screen for a screen sharing product despite a screen sharing tool called screen(1) having been around for decades, so nothing is impossible.
Things that have nothing to do with vim but are inspired by vim are even sprouting up! And apparently it's OK to name something based on vim: https://groups.google.com/g/vim_use/c/EnSMrx_rGg4/m/d_nVlmLQ...
Edit: In Bram's reply he mentioned the household cleaner. Apparently it's similar to Ajax. That's so awesome. https://en.wikipedia.org/wiki/Vim_(cleaning_product)
