Still it should only get online either for an update of the program or when I sync to raid, rest is unacceptable.
Unacceptable? Seriously? No one is forcing you to use Parsec.
You need to keep in mind that this is a free software, provided as-is. If you find something unacceptable don't use it or grab the source code and edit it as you please (under the terms of the GPLv2 license).
You are complaining about something pretty much every decent website in the world uses, including swtor.com.
