Right lets hack a working code, if these issues were a problem it would mean bitcoin is unusable.
Bitcoin at a price of $2739 USD, this says it all, investing in a product that works.
Seems like propaganda, afflict the comfortable with made up issues or perceived threats and announce we are doing it for safety and security
The question here is who would want bitcoin not to work or work in a way that can be corrupted.
Look at the players and funding behind segwit and you will get your answer.
