My hosting account only gives me cPanel, I do not have WHM. And from cPanel I do not see anything to do with EasyApache. That's why I'm wondering if my shared hosting account even uses EasyApache? Is EasyApache only available on private servers?
Regarding PHP changes, on cPanel there is an option where I can select my PHP version on the button where it says "Select PHP Version." If I keep the version that I'm using, 5.6, then I probably shouldn't run into any problems. So just seeing this option in cPanel gives me peace of mind but are you saying that the hosting provider can still somehow make changes to my PHP version?
In the end, I'm just concerned about a forced upgrade from EA3 to EA4 and if it will affect my site. Since I don't see any option for EasyApache on my cPanel, I'm not even sure if it uses EasyApache at all. Should I be concerned or will this forced update not affect me?
