Yes, it's still harassment. You have other means of expressing your frustration at the company, but contacting individuals directly (who may or may not even be in charge of that aspect of the company!) is not a valid way of doing so.
That person is responsible. They make, or oversee, the decision to brick phones for probably thousands of people. Probably this makes even more money for them, as the greater percentage will buy a new phone, rather than reach some sort of resolution. There is no legal comeback for this immoral executive decision. In fact, the legal system will find in favour of the CEO. Their contacts will allow it, and if not, they will lobby for laws to be put in place to allow it in future.
What of any of all that is "right"? It's simple force; right is might.
Do you know what "right" is? Do you think what is legal, is also right?
