Disclaimer: this absolutely sucks and I'm baffled that they've made this move at all.
That being said, I don't think folks have noticed the very specific situation where this is the case:
Users who redeemed digital copies of a Blu-ray or DVD purchased from Funimation were granted access to the streaming service, where they could store and stream the purchased program or film.
They are very specifically removing the free digital copies that came with buying hard copies via Blu-ray or DVD. It still sucks, but no one is losing a digital product they outright bought.
I see where you're coming from, but I don't think that excuses anything. If you bought a hard copy with the understanding that a digital copy came with the purchase and now they're taking away the digital copy, that's still a Darth Vader "I'm altering the deal" type move.
kinda feels like selling someone a burger and fries, taking away the fries and then going "no one lost a burger". the digital copy is part of what was purchased, and its been taken away from purchasers with no recourse. The digital copy was part of the deal.
I chipped in when my friend bought Paranoia Agent on Blu-ray because he promised me the digital copy, so this does affect me. Granted, after learning the news I "found" some rips online for my NAS, but still. It's not okay.
