I would be really surprised that Apple has any intent to destroy Android as they would quickly fall into antitrust regulations. Those would hit Apple really hard.
They are much better off Google having most of the market share and having to deal with those issues
Intent to "destroy Android" is always rephrased in some form like "we want to provide value to customers" and "reach key demographics". I can guarantee you that everyone at Apple (for some convenient definition of "everyone") goes through mandatory training every year on how they should not talk about how they are going to destroy the competition.
That, and all the current big tech players spend equally big money on government lobbying, so absent a smoking gun, I don't think US antitrust action against any of the tech giants is likely in the next 10 years. Microsoft, you might recall, did not have government lobbyists and the lesson that everyone in industry took away was "monopolies are fine, but you'll get in trouble if you don't have any lobbyists".
So Apple's strategy is to make expensive, high-end phones and capture the bottom end with used phones and older generations. You can phrase this as "destroying Android" or you can phrase it as "providing good value to consumers". The strategy can be the same either way, just be careful when you write that email.
