RSA is bad, because developers do not implement it as specified and ECC is good, because most developers will not implement it themself, because they do not understand ECC and therefor use libraries? IMHO a huge advantage of RSA over ECC is it is easy to explain. After you have explained the different kinds of elliptic curves and their pitfalls, you have to explain the integrated encryption scheme to actually use it for encryption. But ok, you want hybrid encryption with RSA too, but in theory, you do not have to.
The article's argument is that because RSA is easy to explain, developers are more likely to roll their own and do it wrong. But that's mainly an argument against "roll your own", for those who aren't expert or aren't willing to take the time to learn all the pitfalls.
