I think Ubuntu made sense back in the day when Debian wasn’t as user-friendly.
This is a very good point.
When Ubuntu launched, it was a big moment for linux. Before then, setting up a linux GUI was a lot of pain (remember setting modelines for individual monitors and the endless fiddling that took - and forget about multiple monitors). Ubuntu made GUI easy - it just worked out of the box for most people. It jumped Linux forwards as a desktop a huge way and adoption grew a lot. They also physically posted you a set of CDs or a DVD for free! And they did a bunch of stuff for educational usage, and getting computers across Africa.
That was all pretty amazing at the time and all very positive.
But then everyone else caught up with the usability and they turned into a corporate entity. Somewhere along the way they stopped listening to their users, or at least the users felt they had no voice, and a lot more linux distros appeared.
You don’t normally have to bleed the brakes after changing pads.
You WILL have to pump the brakes a few times before you start to get pedal feeling back, because you’ll have pushed the pistons back in the calipers and they need to reset, so don’t drive off until it feels good.
