I am fine with "blocklist" instead of "blacklist", because it sounds similar. But "allowlist" is just more difficult to pronounce. Regarding your concern about people for whom English isn't the first language, I dont know how valid it is. Because those terms exist under the same names and fall under the same usage in many other languages. I can confirm that it is the case with Russian, as "черный список" is a commonly used phrase, and it literally translates to "black list", and has the exact same meaning as in English.
