Seems like they're just mentioning one action from Tim Cook take they personally didn't approve of.
Also a11y lawsuits are not only a great way to make an easy $10k a pop, it's a even better way to organize with your local legal teams. They always like easy money IME.
Oh don't forget that you can get sued for the same violation multiple times by different people at once, nice way to collect some money and if you want to attack big tech.
