It looks like the occasion is the 30th anniversary of Bare Bones Software (the company): <https://www.barebones.com/company/>. Perhaps the original submitter mistakenly interpreted the "30th Anniversary special pricing” text as applying to the BBEdit program itself.
The new title now seems inaccurate, or not reflecting the intention, given that, and given that the linked page says "30th Anniversary special pricing! Use the coupon code “BBEDIT30” at checkout to get BBEdit for US$30 for a limited time."
The situation is confusing because of a little bit of history.
BBEdit was 30 years old last year because it really was around in 1992, but it wasn’t commercially available. It was basically Rich Siegel and his friends. 1993 is when it became commercially available at version 2.5.
This doesn't say when exactly Bare Bones Software was founded.
The anniversary celebrated was the commercial version of BBEdit released on May 11, 1993. Not the anniversary of the company. Not the anniversary of the the non-commercial version.
Sigh. I don't really understand why you're having such trouble with this?
"BBEdit is 30 years old as a commercial product"
"30th anniversary of BBEdit as a commercial product"
"Bare Bones Software released the first commercial version of BBEdit 30 years ago"
Plenty of fine, accurate, straightforward titles to choose from, yet you keep doing weird, misleading stuff with it.
In fact, the original submitted title was fine, and clear enough.
It's apparently true that there was a free version of BBEdit released on April 12, 1992. But that is not what is being celebrated now. It's largely irrelevant. Rather, it's the non-free version released on May 11, 1993. That's why there's "30th Anniversary special pricing" of $30 with coupon code “BBEDIT30”.
30, not 31.
BBEdit, not Bare Bones Software (the exact anniversary of which is unknown).
(Submitted title was "BBEdit is 30 years old")
Edit: some people didn't like "BBEdit is 31 years old" so I took another crack at changing it.
Edit edit: never mind.
