So... do the ubiquity things work again without being tied to their 'cloud'? Fake vulnerability or not, this is the worst part about their devices these days. Speaking of which, are there any semi-pro APs that still work without going through the vendor's servers?
Ubiquity works without their "cloud" if you install their management software on your computer (I use a VM on my server). In my experience, you don't even have to run their management software once you have the network configured. If you are paranoid, install their s/w on a VM, set up your network, and then shut down the VM. You should bring up the management VM periodically for software updates, but otherwise it runs fine.
