It's the same question foreign companies wanting to serve the US, Russia, or China already have the answer. It's not a difficult position: the money almost always wins.
For instance, Apple has modified its Chinese iMessage software so that all data is always stored on Chinese servers (though it's technically still end-to-end encrypted, they're the only permitted e2ee encrypted app, so I assume something shady is going on there). Apple also added RCS to their iPhones because China demanded support for it (RCS isn't e2ee of course). When big governments demand changes, even the least evil big tech companies are willing to bend the knee as long as their business model doesn't break.
