Clicking out of it is fine. It's the fact you have to do it daily.
And something else new I noticed just in the last 6 months - while this window (to skip trial) is open, Evernote actually consumes 24% CPU usage. It's specifically that, because, upon clicking skip trial, the CPU usage goes back down to expected levels. I don't mean closing the app, I mean clicking skip trial - this notification for whatever reason consumes a quarter of my i7 CPU.
