"Look at the code" is an anachronistic strategy. Nowadays, very little of our data solely relies on our own devices, and most of the value of consumer software occurs when data is being transmitted between systems. When your data lives in the cloud, there is almost always a side-channel way to get at your private data that won't be visible in any Git repository: Just go look at it directly. Meaning that, nowadays, if we're to live any sort of non-Luddite, Internet connected lifestyle, all we have to go on with anybody is their word. If I limited myself to services where inspecting the source code would give me what I need to know about how well my privacy will be protected, without trusting the word of any third parties, then I'd have to let go of email, telephone, and credit and debit cards (and banking in general). Plenty of other things, too, but I think those three paint the picture well enough.
