Before you do that, try replacing the EOSSDK-Win64-Shipping.dll file with an emulator (in the flavour of Goldberg).
Fun fact - Nemirtingas made exactly such a thing, but it's really hard to find a copy! I ended up finding it in "Nucleus Co-op". Get the zip, don't bother installing it, just yoink it out of the utils folder.
I can personally attest that "it hasn't cryptolockered me as of this moment", for what that's worth.
Epic hasn't gone out of their way to make life hard for Legendary/Heroic, yet. I guess that is a kind of support.
My biggest regret with Epic is buying Eastward there, and then whoops the DLC sidestory is available on every store but there. I can only read that as meaning "nobody makes money selling games, to the end user, on EGS. The only money you'll make is from selling directly to Tim Epic for a giveaway or an exclusive."
Am I going to put any more money in Epic? No. Am I going to take the freebies? Sure.
