the problem is that most or almost every professional programmer goes by the slogan "You shouldn't implement cryptography by yourself, but instead rely on the existing well tested libraries". This is hinders competition in the crypto space. You definitely cannot say that the programmers of openSSL are not professionals, because you know that the majority was relying on their library so it is definitely the best library out there. There is just no better alternative. if you want to have alternatives then you have to encourage amateur crypto programmers to implement competing products. But the whole programming community is doing the opposite by bashing people who start implementing their own crypto. For example If I remember the debate about Telegram where a highly talented team starts their own library the response from programmers is that they shouldn't do this and instead use crappy old libraries which do not even fulfill their requirements.
