I have somewhat enjoyed being able to view all the games I own in GOG galaxy, since I can connect my account and have all my games form other services displayed.

I was thinking about connecting my PlayStation account, but the integration plug-in thing isn't listed as an official one, but a community one.
I'm thus concerned about supplying my account credentials to this. So I ask, who exactly is operating this thing? Who is making this integration? Who is taking responsibility for it?

For that matter, why is there not an official integration? If the community is able to create an integration for the PSN, why can't GOG make one themselves?
