Careless and rampant memory use. Why is CoreSync using > 1 gb of RAM?

This account is a few months old.
I've made maybe 10 illustrator files.

And here's CoreSync.exe sitting on 1.1GB of RAM. 

I haven't used Illustrator since rebooting, and it's not the first time it's done this.

I wouldn't mind it using e.g. 1/32 or 1/64 of the system's RAM, but it's not actually doing anything.

Then there's the AdobeNotificationClient, AdobeUpdateService.exe, etc

Guys, it doesn't take this much time, or this many resources to check if:
A- my license is valid
B- there's anything to sync
C- there's anything to update

Then after opening and closing Illustrator, it pivots to downloading 1.6gb of updates.
If it was already sitting around doing nothing, why wait till I'm done, and moving on to a new task, before hogging all of my bandwidth.

A few minutes later

Crossing my fingers for a time when there's are enough opensource disruptors that Adobe is forced to step up their game and drop the heavy handed act. It just feels user hostile, tbh.


p.s. this doesn't show up until you hit "preview".
