Let's see how a link like yours looks like (assuming it's the output you're worried about): pad.lv/1532508 vs. bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1532508 – that's quite long, but the long one contains useful information: It's on launchpad, it's a bug report, it's about gnome-shell. The short one does neither. Doesn't matter at all if you use a meaningful(!) alternative title (see above).
Why do you find it useful? I usually use an alternative title, e.g. see [this launchpad bug](https://bugs.launchpad.net/…), where there's no difference in the output. Is it the comment's character limit or the actual output you're worried about?
It's supposed to be “via email, Google+, Twitter, or Facebook.” and that's exactly how I see it with Vivaldi, uBlock Plus and Ghostery. Did you try disabling uBlock (just for testing of course)? Do you have any userscripts (Greasemonkey/Tampermonkey) enabled that could case the issue? Or anything else that blocks social network stuff?
Exactly like in your Ask Ubuntu post you don't ask a clear question but merely write a rant, and that's not tolerated neither there nor here. Come back when you're ready to express a real question, I suppose something like “Is the data collection enabled by default in 18.04 compatible with GDPR?” would match.
Thank you for researching this! I had the badges in mind, but wondered whether this really is the only reason. It seems a bit childish to me – I cherish gamification, but making (short!) links as short as possible is much more important IMHO.
