Mastodon is not a platform.

You took a few expected disappointed replies as a representation for many more. I am pretty sure there are corporate (including Facebook's own Threads) instances that will praise the post. Other people already have.

It is not toxic to be disappointed or critical of an action.

People join smaller decentralised networks to escape Facebook. They pay the price of the network effects. If they are disappointed by software contributing to one of the locks people face in the networks they escaped, it is not toxic nor is it even an unreasonable position.

Having a presence on proprietary, locked-down platforms contributes to the current status quo of people being stuck inside them. It is not toxic to point that out. In fact, I think it is toxic to hand wave away legitimate concerns about contributing to predatory platforms that always carry the same pattern of embracing as many people into their networks as possible, then locking them in.
