Comcast still blocks port 25. And last week, a locally well-known person was blocked from sending outgoing port 25 email to their servers from her home Comcast service.
MSA port 587 is only 9 years old. I guess it takes some people longer than others to update their practices.
You missed the "to their servers" part (I don't think it's singular "they" 8-). At the intra-ISP level, submission vs. SMTP does not really matter because it's all local policy. If they block her on 25/TCP on their own servers, they can easily block her on 587/TCP, too.
