I don’t trust any graph without at least its axes and captions, so here’s the source.

While I think the message here is important, this particular plot seems to be of “Owner Occupier’s Housing Costs” and this capture conveniently crops the frame so that you don’t see the dip just before 2019.
Permissive licenses permit a broader range of use compared to “copyleft” licenses.
“copyleft” here just being a cute way of being the opposite of copyright - instead of disallowing others from what they can do with “copyrighted” code, “copyleft” requires that they (upon request) share modifications to your code.
Permissive takes away this requirement to share your modifications. “copyleft” is considered more free and open source (FOSS), permissive is more business friendly.
