I appreciate the warning but I don't feel like the author added anything besides the usual "crypto is difficult, stay away from it". I completely agree with it, but as a developer I didn't get any advice on how to operate in that situation. I can't tell my boss "no, I won't do it because someone on Twitter said I shouldn't".
