"A May report from news non-profit The Markup concluded that Amazon, Apple, Google, Meta, and Microsoft often support privacy in public statements, but claimed that behind the scenes the companies have worked to weaken or kill US privacy legislation. "
While Big Tech companies may be supportive of abortion rights for their employees, they might be happier to support that to be enacted by law rather than have Roe v Wade still stand, given that Roe v Wade essentially expands the borders of what 'privacy' is normally considered to include.
It's completely unlikely that any of them will limit their data collection golden geese to protect their users' privacy, whatever weasel words they will come up with in public to pretend otherwise. And they all typically already comply with legal/judicial data requests, so if a Texas court subpoenas a dataset from them, I don't see them refusing if the warrant is legit and the data is available.
Incidentally, I don't know how the warrant details work, but if a judge issues a warrant for the location data of Mrs Jane Doe over a specific time period, would Google etc even know if it was in relation to an investigation on abortion vs say grand theft auto?
