Freedom of speech is good. White supremacists or any other group ideological supporters will always find a way to communicate and share their message, regardless of the century, technology, or censorship. Frankly, doing this openly on X/Twitter versus some obscure unknown forum or encrypted platforn is a positive. Social media as a whole is susceptible to ideological campaigns from groups and other countries, not just X/Twitter.
!! I love LilyPond. Found in back in 2010 when I installed Ubuntu for the first time and wanted an alternative to Finale…first OSS software I probably knowingly used. I felt like a real coder typing my music. Frescobaldi is a nice compliment to LilyPond. I still use LilyPond to this day
