I guess we all have our opinions. I just really hope that E-bikes, including E-assist, be scrutinized a little more when being in places where traditionally non-motorized vehicles are used. And the tolerance of e-bike/assist be extremely limited on those trails. Non-motorized multi-use trails with elderly, disabled, and children should to be kept non-motorized.
Hiker/biker camp sites should be for traditional non-motorized modes of transport. This would exclude E-assist/bike.
Just my opinion.
Now tour on!
If they are in the bike lane, bike route or shoulder of a roadway, fine, as long as they fit the state/country requirements for being in said lanes and follow the rules (whatever rules of the road are...).
