This isn't the same thing at all.
When the other titans don't have that feature, they have less of a stake in the argument at hand.
Their business model is to sell ads to 3rd parties based on the information they have about you. Selling your info itself would be detrimental to their business.

Making money from targeted ads doesn't mean they think the FBI should be able to bypass device security via hardware and software vendors.
Basically: making money from data != believing that a right to encryption doesn't exist.
