English spelling and grammar are fluid, and have ever been so. At any point the "rules" reflect the accepted custom and practice of the day. You only have to go back and read the writings of Shakespeare, Chaucer and more recently, PG Woodhouse to see the evolution of our language.
Many other countries, including most European states, have Government departments that pontificate on and rule on the use of their language, with less and less effect.
It is my belief that because English is owned by its users it is the most common second language and a major first language. OK, some of the way English us used by people from other countries may make some of us uncomfortable, but rejecting a job candidate because of their use of English could be seen by the ever more sensitive Woke generation as being racist!
