Some privacy advocates will equate the two things, but personally I find that reductive and misinformative. A centralized identification system
can be abused, in the same way a central bank can. Where privacy can impact such a thing is through regulation and separation of concerns. It doesn't look like when this programmer worked on the system that it was purposed for abuse, so I don't know why this Twitter user thought it appropriate to equate the two. Without knowing that, this discussion is basically moot and this Twitter post is typical Twitter mud-slinging.
The real concerning part, to me, is that one person thinks it's okay to make baseless accusations about abuse and named the developer, which can endanger their well-being and their career.
