Companies are free to set their own prices. Setting a price that matches your competitor's price is a standard business practice and is not considered price fixing as long as there was no coordination with the competitor.
In other words:
1. If Apple went and talked to Google and Microsoft and they all agreed to set the price to 30%, that would be price fixing.
2. If Apple looked at Microsoft and saw that they had set their price to 30% and decided they wanted to do that too, that is not price fixing.
