How does this commercialisation impact the OpenSSL mission?
It doesn’t. OpenSSL is not being commercialised and there will not be separate “paid” and “free” versions of the software. The OpenSSL mission of providing a high quality open source cryptographic library for use by anyone under a very business friendly license will not change. The same OpenSSL team members will continue to improve and maintain the OpenSSL product for general use as always. The only commercial aspect that has been introduced is that corporate, institutional, and government users now have the option of purchasing commercial software support for the same open source product that is freely available to everyone. These paid support subscriptions help support the OpenSSL team members actively working on the OpenSSL product and so indirectly benefit the entire user community.
