Twitter blocking links to Mastodon and other networks reminds me of when (10 years ago!) they also shut down Instagram’s “find friends on Twitter” feature. But you know what you can always link to in your profile? Your blog.
@manton.org -- it should be one of the rules of textcasting, except for abuse, if i put a link in my text, you have to display it and pass it on. abuse is a subjective idea, of course, but you should not be required to pass on a link to child pornography for example.
