I quit PF, along with shooting, around 2017 also. I was never a frequent poster, but was an avid reader.
I rejoined in mid-2022. While much has changed, much has stayed the same.
Looking around at other forums I used to frequent, they're either largely inactive or not worth spending time on. On PF, you can still find well reasoned arguments and debates born from direct, extensive, experience. When I was looking at re-baselining to where pistolcraft has evolved in the last five years, this was still the first place with content I digested as well.
