The reason people are bringing up cloud is because it's what effects them. If you have (cloud) access through a company to local devices and that company is hacked then that could be a very wide pathway into your local set up. The company being hacked and related implications is still not great for a huge list of reasons but it's the possible local breaches that are more of a worry for a lot of us.

Ubiquiti has recently been pushing there cloud set up (to the point that you can't set up a local controller with out setting up a cloud account) that's why it's so annoying.

*There is probably a way but the last time I tried I couldn't find it in setup and so installed using a previous version.
