Some people outgrew the server, other people grew to hate it.
Admins did nothing in the way of fixing servers (Vanilla, EZ, Factions, etc.) and some people eventually got sick of it. Sandbox has also not been updated to the newest version in forever, and there's constant lag issues.
It's kind of rash to start a server and then stop supporting it without any further notice, and it's especially frowned upon when you have donators who are actively paying for ranks on the server.
"SKrafty is not supported"
I hopped on today, and after a couple minutes, I agree to disagree with this in some places. Yes it's not getting the activity as much as it has, but they've
* Maintained sandbox, miniwalls, turfwars, skville, ez, bedwars, paintball, blockparty, arenabuild, battleroyale, arcade, skyblocks, amongus, and kitpvp. All of these games are (mostly functioning) unsure about server lag. This is more than enough for any server
* The hub is fine. A little quirky, but alive. They added a new NPC in the hub for taskmasters
* They have added two new games recently, blockparty and sheepquest
* Added new bedwars maps
* added new skywars maps
Some of these things seem like really really tiny things, but when you're balancing out your real life situation (and that's more than just family, i've learned that recently) the amount you can do becomes smaller and smaller.
It's gotten some new games and updates. The issue is, (technical issues with updating versions aside because they exist), people just grew out of SK and also left because they found/made contact with others off platform on different instant messaging platforms and just simply don't want to play SK and instead play other games. I'm 100% aware that probably violates their rules but most of the older skrafty folks definitely did that, me included, and opted to play different games.
Of course, on the contrary I do think there could have been drastically clearer amounts of transparency on various levels, I don't think the EDU costs should have been increased personally, but I feel like I may not know the full picture of that. (the EDU was the huge reason lots of kids came to SK, we stopped using the EDU because it just cost way way too much for us [more than buying several books that my mom used to self teach me and my siblings k through 12], which said a lot).
Everything else I partially agree with. But I do come from a bias, I helped with managing the support/backend of a larger MC factions server that shut down due to the owners just not having the time
