People often use the OSI’s Open Source Definition when using the term “open source”. One of its criteria says “The license must allow modifications and derived works” which this license does not allow.
https://opensource.stackexchange.com/questions/8367/is-the-term-open-source-a-trademark has a discussion about this.
The short story is that the OSI failed to obtain a legal trademark in the US for the term “open source” (software), resulting in many opportunistic companies and individuals adopting the term popularized by the OSI (which was founded by Eric Raymond, Michael Tiemann and Bruce Perens).
There was controversy at the time due to it being a business-friendly spin on the ideological “free software”, and I personally avoided using the term for many years as a result. Even without a trademark on the now generic term of Open Source, there is still value in the OSI brand and its stamp of approval on a license.
Those who want to be crystal clear, should probably always say OSI Approved Open Source License.

People often use the OSI’s Open Source Definition when using the term “open source”.
Which is one of the possible definitions. Mine is “you can see the code”. Everything else falls into “free software”.
That’s nice. If your goal is to ever talk to people about open source software, that’s going to create a lot of unnecessary confusion.
On top of that, accepting this bolsters companies to use this kind of a definition specifically to take advantage of the mental model that many people have connecting “open source” with OSI.

I guess that my definition of open source is not that uncommon, given that the terms “free software” and “libre software” exist and are rather well-established by this point.
