Apple could fix this if they wanted to, but they don't want to. They know it sells phones. It is intentional.
It was to mark the "plebs" so the "plebs" would be blamed for any issues rather than Apple.
Phone plans used to come with a limited number of SMS messages per month (or even none), and the rates per SMS if you went over the limit were beyond extortionate.
>Since BlackBerry messages are sent as data, users do not incur individual charges for each message as they would through regular SMS texting. While phone companies have introduced bulk texting plans, many options still include caps on the number of individual SMS messages that can be sent. BBM has no such limit.

But wasn't cellular data priced similarly extortionately back then?
Before iPhone or Android existed, Blackberry was very popular with teens because you got unlimited messaging on Blackberry Messenger included with the data plan you got with a Blackberry.
Eventually there were cell phone plans where you could add unlimited SMS for an additional fee regardless of what phone you used.
By the time the iPhone rolled around, all the American iPhone plans included unlimited SMS messages without an additional fee.
I guess it depends on your terms. I had--I think--a 2GB per month data plan (which was actually fairly reasonable for mobile at the time) and later went to "unlimited" but I was still paying something like 10 cents per text for a time. I didn't text a lot so I just paid a la carte until I changed plans.
Communications charges have changed a lot over time. I remember when long distance calls were something like $1/minute.
I can remember Verizon being sued because they forced handset manufacturers to disable Bluetooth for file transfers, because Verizon used to charge you money every time you transferred photos to or from your phone.
iMessage was released 11 years ago now. Can’t blame Apple for what not considering what the toddlers of the time would eventually do with the technology.
This is what people in the hate-Apple echo chamber like to chant, but it's wrong.
When Apple started doing it, there was no network effect.
The color choice was made years before everyone started freaking out about green and blue bubbles.
It was done to show that a message went over SMS, and not iMessage at a time when many Americans paid for each SMS sent, but iMessages were data, and thus included in data plans.
It served as a warning that you were spending money. I suspect that's why it's green.
