Why are Photoshop & Lightroom Classic now requiring me to login?

Everything else is by subscription only. A log-in is not snooping but it is necessary to ensure your subscription is in good standing.

Not sure why you say that logging on enables snooping. Before it stayed logged in for longer, but you’d still logged in. 

Turns out there are new 'security' protocols in place & I had to sign out of the Adobe Creative Cloud Desktop app (I'm on Windows 10 Pro) and re-sign in. - And we'll now have to sign in again every 30 days.

Adobe's always had very painful activation procedures, then they screwed us by forcing even occasional users to pay monthly - whether they released any new useful features or not - and now I wonder if they are finding another area to muck with out lives. Sigh...
