No, you are just oversimplifying the issue. Of course, if you were regularly riding before and very fit and change to an e-bike out of laziness, the net effect might be negative, tho even that part is not conclusively proven.
But if you found biking way too exhausting, maybe living in a hilly area, riding an e-bike is ten times better than doing nothing. Would it be even better to ride a non-e-bike? Maybe. Would it happen? Probably not.
Being daft on purpose? I haven't heard that using an alternative browser suddenly increases the traffic that a user generates by several orders of magnitude to the point where it can significantly increase hosting cost. A web scraper on the other hand easily can and they often account for the majority of traffic especially on smaller sites.
So your comparison is at least naive assuming good intentions or malicious if not.
