I'm in public tech for 13 years, making 200k per annum.
Advantages of public tech - protection against foreign talents, protection against ageism. I still get to code with minimal project management. So I do what I like, with a decent salary, good work life balance, good job stability.

The advantages of public tech appear in the later half of career, I'm not worried of getting retrenched at 50.

Some things to consider. Career lifetime is a long time, plan strategically.
