Does anyone believe in "change from the inside" any more?
From a "change from the inside" perspective, Apple can make more of a positive difference in pushing forward their agenda for countries like Russia, by staying in the Russian market, complying with a few government demands, and thus offering a sub-optimal form of their products/services—but still a form that has nonzero privacy/democracy/etc.-enhancing effects, relative to the alternatives that would fill the market in their absence.
For example, iOS devices at least have a universal base image where Apple knowingly makes these changes, and as few of them as possible; whereas Android devices get their firmware tampered with in each country by that country's OEMs, and so can be made arbitrarily compromised, including making those same changes to the maps on the client side.

Or, to put a finer point on it: a company like Apple that offers privacy/security-enhancing products, opting out of a market because that market's government sees them as a threat and wants to neuter their abilities, would be like a peacekeeping organization opting out of a country because of the very things that make countries need peacekeeping (e.g. a failed state.)
Would you pressure KFOR to leave Kosovo because the Kosovo government doesn't let them do their jobs? No, that'd be reason for them to stay.
What's suddenly different if it's a profit-motivated corporation? They're still helping citizens evade state surveillance, even if entirely for selfish reasons.
