As an unpaid volunteer to a multimillion dollar corporation that has just erased a huge collective volunteer effort, listing in writing the reasons I'm unhappy is already way too much effort.
Asking that same volunteer to hop on a video call is just insensitive. They're the one providing free work; if you care about solving the problem and not losing the volunteer force, you should go where they are (the forums) instead of asking them to come to you (video call). They probably don't want to take time out of their schedule to waste their time talking with a community rep. And they probably don't even want to do a voice/video call.
