I would say that anyone who ever tries to encrypt some data and does the bare minimum google/stackoverflow search for how to do it would see extremely vigorous warnings not to touch ECB with a 10 foot pole.
Unfortunately, crypto libraries have a history of having a terrible UI and defaulting to ECB. Years ago I ran into this with pycrypto. I worked on a team that joked about how important it was not to do ECB and it turns out they had done ECB. https://www.dlitz.net/software/pycrypto/api/current/Crypto.C...
