Chrome - updates secretly, breaks stuff that doesn’t’ get fixed for months, if at all
Discord - Updates all the time, no change log, can’t tell if our members that take forever to start-up are having problems with an update or not… somehow we get on different builds.
Android …
ProFantasy - doesn’t seem to update in the app, gotta go get it like it’s the 90s.
Marvel Heroes really was horrible. With an update client updating itself in the worst way before trying to update whatever it was updating and… eew. I think EVE must have been their inspiration (although I think it changed a few years ago).
Chrome is horrible for the precise reason Nesrie described. One of such highlights I remember was when Netflix stopped working properly for a month.
SWTOR will only let you update the client if you are signed in, which means the client can’t background update. So, even if I get the urge to try it out again a few times a year, there’s a huge patch to install which means I’ll be unable to play until a point in the future when I’m not really interested anymore. Argh.
The Standing Stone (LOTRO, DDO) patchers are bad in that they have a bunch (4+) of sequential updates to 1000s of files at a time.
Copying/updating individual files takes far longer than a single large file. Each time, just as you think you are done, there’s a couple thousand more:
I miss GameSpy, FileFront, GamersHell and FilePlanet for all that cheap file hosting during the dotcom rush. They all collapsed after the money disappeared well before patching went to online-only.
