At this point, I think all of the big tech companies have had some accusations of them acting unethically, but usually, the accusations are around them acting anticompetitively or issues around privacy.
Meta (and social media more broadly) are the only case where we have (in my opinion) substantiated allegations of a company being aware of a large, negative impact on society (mental wellness, of teens no less), and still prioritizing growth and profit. The mix is usually: grow at all costs mindset, being "data-driven", optimizing for engagement/addiction, and monetizing via ads. The center of gravity of this has all been Meta (and social media), but that thinking has permeated lots of other tech as well.
