It stemmed from the DisUnplugged show today. Pete said Primeval Whirl/Rivers of Light were probably closures due to covid, but not necessarily safety related closures - more likely they were money related closures. Convenient reason/timing to get rid of some of their more difficult (due to maintenance, lack of interest, expensive to operate, etc.) attractions and offerings.
Pete said he's expecting to see more attraction cuts along with an increase in food and merch prices as Disney tries to trim costs to make up as much ground (money) as possible. Things that they wouldn't have been as concerned about in a bumper year are now potentially things they'll cut (permanently or temporarily) as they try to recover from covid impacts. Pete did mention CoP specifically, saying he wouldn't be surprised if that is one they cut.
