If you were asked to provide eg 1MW of additional electricity right now, the cheapest way to do it is with renewables. Wind and solar is currently cheapest to install and operate per MWhr of produced energy. All other forms of electricity production are more expensive to install and have much long lead times from planning to building to commissioning.
There is no path from the world we are in now, to a world where all energy is from nuclear sources. You would be asking those industries to invest in less cost effective technology. There are lots of (surmountable) engineering issues to resolve with grid scale renewables, but the bottom line is that new installations are nuclear/coal/gas infrastructure are going to be decreasing over the coming decades.
There are similar issues when considering biomass as a stand-alone heat source. There are fundamental limitations on massive national populations depending on biomass for heating and energy. In areas where it is plentiful and populations are sparse it can be great. But it simply cannot scale to high density urban population centres without massive environmental and human harms. It has already been pointed out that the logging industry has a non-trivial annual death rate. Massively expanding this in a world where biomass is used more extensively will lead to greater loss of life. Similarly, those logs need to be harvested in forested areas and transported to urban areas for use. Thousands more lorries on the roads, with implications for traffic accidents, urban air pollution etc… and this is before we even get to start burning the fuel in whatever stoves people are using. Large scale biomass burning - even in rocket stoves - will have an impact on air quality in urban areas.
The UK historically depended on wood for heating, but transitioned into coal during the industrial revolution. Deforestation was rife, and there were strict laws in place regulating who could take what timber. In the modern era, despite massive increases to population size and density, we have more total woodland in the UK than at any point for hundreds of years. switching to biomass would likely trigger an environmental disaster as deforestation runs wild.
My personal view is that hybrids will pretty much always be the queen forward. We burn wood because trees keep falling over on our land. If we don’t burn it, we have to do something else with it. It is a waste product for us being diverted to a higher purpose. That rationale cannot be applied universally.

While I agree that there are some evil people (anti-humans), I can't see how they could regard permaculture as a threat. I've gardened organically since the mid-1970s and subscribed to Organic Gardening magazine for years but wasn't even aware of permaculture until the last decade. I'm pretty sure that it's still a fringe endeavour in the big scheme of things.

A corporate troll is to persuade the observer that their employer's message is good and others messages are not good.
I'm sure that it's clear to all permies that being helpful is your primary motivation. It's also obvious from your description of the negative pile-on that you're being trolled. But I can't think of any reason for commercial/corporate actors to be involved, because I can't fathom why they could see you as real competition. I think the trolls' motivation is similar to that of outrage mobbing on social media -- mischievous, and worse, group action bolstered with schadenfreude. In other words, the bane of (anti-)social media. Proclaiming misinformation is part of their fun.

The trolling blowout you described is disturbing. Do you know of others who have experienced such a thing? It certainly sounds organized -- but by whom?
It doesn't seem plausible to me that any corporate "competition" would feel threatened enough to bother. It's puzzling, but I wonder if the troll storm was a test of a nefarious tactic for disrupting a social media platform and you were just a random target.
