It seems that both had alleged collaborations with PRISM. The main difference I see between the two wiki articles, is that people complain about Microsoft's telemetry but not Apple's (even though they do have a lot of telemetry [1]).

In general it feels like Apple has won the trust of the public, partially through good products, partially through good marketing.
