I read Tor's Wikipedia page and found out it has 12 weaknesses. What can people or The Tor Project do about those weaknesses? If they don't anything about it, wouldn't it compromise Tor users' anonymity?
No anonymizing service is foolproof. To prevent yourself from being deanonymized by the abuse of tor weaknesses you should do the following:
Maintain good OPSEC.
Use security focused OS like tails or whonix.
Finally chain multiple anonymizing services over relying on just one service like tor alone.
