Again, it wasn't about "WP", it was about "WordPress" (and "WooCommerce"). Don't focus on "WP" just because the company name is "WP Engine". It's not relevant to this matter, their claim of trademark infringement is about "WordPress" and "WooCommerce", not about "WP".
Unfortunately many of their public statements have focused on the "WP" in "WP Engine". See my above comment.
Their messaging around this has been messy and rambling. The drowning out any point they're trying to make with their own messaging.
Who can say the offer "WordPress" hosting? How much do they have to pay? That question was dodged several times in the interviews I've listened to.
If it's a trademark issue, make the claims and let the courts figure it out.
Stay focused or stop talking.
