Informing you on Facebook does not really inform other “Pinegrow Wordpress” users however and certainly does not coincide with the promise of openness in 2020 by @matjaz.
If they informed you a few weeks ago and knew they were choosing to lock their products into ACF PRO for Gutenberg Blocks. Then when “Advanced Custom Fields” announced on February 16th that February 24 would be the actual date of the pricing change and they subsequently updated the blog post with that actual date (absent of ACF stating the time of expiration which was added to the blog late on the 23rd to accomodate the timezone debacle). Then the PInegrow team had a clear opportunity to make this announcement directly to “Pinegrow Wordpress” users an entire week earlier and not less then 24 hours before the pricing change for the mandatory ACF based upon their workflow decision in their products for Gutenberg Blocks.
I find that extremely hard to ascertain if they were hinging their products directy upon ACF for this feature. Other people whom use ACF in their products were making users aware of it directly after the February 16th announcement that February 24 would be the date of the pricing switch. I don’t think @Emmanuel is that oblivious to the WP community and would not have known until less than 24hrs.
Its merely a matter of principle and courtesy to the “Pinegrow Wordpress” users. Sadly they again fell short on this opportunity of informing users properly regarding a feature they were already aware of.
