Big tech companies generally care about security because most of the time, it aligns with their self-preservation. They don't want their secret sauce leaked, they don't want internal mails and payroll posted on the internet, they don't want their users hurt. It's not "top priority", but security probably shouldn't be your top priority; if it is, there is only one winning move: don't build anything. That said, security often ranks high, especially if the company had a couple of close calls before.
In contrast, preserving privacy is often in direct contrast to business goals. You want to preserve it to some limited extent to maintain user trust and avoid offending the regulators, but there is a constant business pressure to get real close to that line.
Big tech companies care about profit. That's fine, they're companies. If security - or a pretense thereof - is needed to increase or safeguard profits, only at that point do they start 'caring' about security.
With privacy it's even worse. Think Apple cares about privacy? It's just - currently - aligned with their product strategy.
