Do you dislike it when people write "yeah" as "yea"? I know someone who always writes "yea" in texts when they mean "yeah". "yea" is a different word with the same meaning, but a different pronunciation.

I do not know it is different, so can't say that.
But could you explain more what you feel or what it mean to you?

Usually, in my experience, people write (and say) yeah, which is pronounced more or less like แย. Yea is usually used in more archaic contexts as far as I can tell and is pronounced more like เย.
