That's unfortunate. FWIW I don't disagree with you, full plaintext links should be posted anywhere. It's not like there are any psychopaths out there typing links manually instead of copy/pasting.
Markdown is an accepted and implemented form of posting content on lemmy. That’s why I can do this or do this or do this but you don’t see the html. The platform shouldn’t cater to you because your app is incapable of showing you the links people post in markdown format, find a better app, or petition your app developer to handle links better
Ok so file an issue with lemmy, https://github.com/LemmyNet/lemmy/issues, stop blaming software because you are mad that html has a feature to put links on text and it disrupts your workflow to see what those links are
