Idk how you're jumping from acquisition to removal of content. If anything Microsoft will either milk IPs or let them rot just look at Rares IPs after they were acquired, most of them were left to collect dust. Sony until just recently has been almost as strict as nintendo with their IPs being exclusive to their consoles not to mention what they did with the content roll outs when they temporarily held the destiny ip locking it away from the rest of the community for like 6 months.
