Apple’s green text messages and non ADA compliance

When will Apple fix the green to white text contrast for text messages from non-Apple devices? I know they can, and it seems like it’s ignored on purpose to deter use of standard text messages in lieu of iMessages. Yes, the contrast in settings can be changed, but everything else is perfectly fine. This is such a small fix, yet Apple has never fixed it. Why is that? Sometimes I have to squint to read those green Messages, and it’s nearly impossible for some family members to read them at all… and this is referring to all devices, not just iPhone.
