> Probably the worst offense is choosing the weakest TLS version + cipher to save resources, like using TLS 1.0 because it take less resources to decode/encode than TLS 1.2 + elliptic curve. This isn't true. It takes less resources to use ECC. Vendors use TLS 1.0 because they use outdated software they haven't updated in ages.
