Look those words up in the dictionary and they won’t have the diacritics, except as an alternative spelling. They’re loan words, and it’s a stylistic choice.

Ask 95% of laymen to write those words and there will be no diacritics, and the language is defined by its users.

Sure, let's look them up in a dictionary: https://www.merriam-webster.com/dictionary/resume

résumé (noun) variants: or resume

Nice of you to skip over the first, primary entry and select the secondary entry. The primary entry has no accent characters.

[jcranmer]

The first entry is for "resume", the verb, which is a different word than "résumé", the noun. Note that none of the definitions provided for the verb "resume" would come close to working where someone intends to use "résumé", the noun.
