This isn't some unique Meta or VR. These are growing pains of new tech. This is what happens with all new tech. We'll see dozens of companies grow, die, and be acquired, and dozens of products change hands and disappear. This is the MO for all new tech that all of us are intimately familiar with.
In this particular case, with this particular product and company, the churn has happened, and we should see some stability now.
If you want complete stability, you're in the wrong line of work, and definitely on the wrong website. But there's no reason to be irrational about it.
