Does it bring you self satisfaction saying it's "abandoned"? Akria no longer does forum support and unless someone specifically forwarded this thread to EKWB, then it's kind of expected for them to not be able the follow the hundreds of forum threads requesting support for their product on tons of different forums. It's making it look like you have beef with EKWB but no substance.
Before crying abandoned, I'm sure you forwarded this thread to them requesting help right?
Had had plenty of "substance" clogging my water blocks I assure you
