Incomplete combustion is much worse, no question there. But burning in facility design for that is really clean.

Climate change won't destroy life on earth, the very worst case according to the IPCC is a billion death by 2099 but nature won't care. Sure some species will disappears but looking at bikini atol, 40 to 50 years after the disaster the remaining one will fill back the newly open ecological niche and the intense genetic pressure will assure that they will eventually diversify.

Since we don't know about the effects microplastics accumulation long term effect, the worst case is that at that there exists some threshold that make higher life form impossible, maybe that threshold doesn't exist but maybe it does. Since humanity won't stop using something so usefull, without plastic millions of peoples would die every year from cause like food poisoning and lack of medical advanced medical care, so cleanly burning the plastic is the ethical choice. As grim as it sounds preventing the possible death of everything is better than preventing a billion death.

And note that I don't suggest that we ignore the 3R, we should still reduce and re-use the plastic and recycle the kind that are truly recyclable but between the landfill and energy producing plastic incinerator, the ethical chois is clear.

I didn't say destroy life, I said destroy our civilization. With current global warmig trends, countries like Bangladesh will be rendered virtually uninhabitable by the end of century, leading to gigantic mass migrations that will likely lead to wars and other issues.

I also wanted to answer this. This is non-scientific BS based on literally nothing. Risks don't work like this: unless you can quantify them, you can't act on them. Any activity has some potential risk of unknown catastrophic effects. Maybe there is some chance that after a threshold, flushing our toilets will cause tidal effects that rip our planet apart - it's unlikely but it's possible. So let's all stop flushing our toilets. And stop using 5G if we're there, some people think that has a high risk of causing cancer or whatever.
