According to one of its employees in Years of Living Dangerously documentary (https://www.youtube.com/watch?v=ORnA5ZdWMWQ), Unilever is one of the biggest buyer of palm oil all over the world, especially from Indonesia. It uses 1.5 million tonnes of palm oil, which is 3% of global production, per year. Yet for quite some time now it has stopped buying palm oil from companies that are actively destroying forests in the process. Paul Polman (Unilever CEO), as one of the most forefront global business leader in sustainability who is also active in World Business Council for Sustainable Development, has been working on sustainable consumption through its Unilever Sustainable Living Plan (https://www.unilever.com/sustainable-living/). So this one is a multinational company and I would, to some extent, agree with your point that companies take advantage of economic growth in less-developed countries.

Another one is Wilmar International, a Singapore-based palm oil trading company which is said to be managing almost half of the world?s palm oil, and known as buying it from many illegal loggers. It was ranked as, environmentally, the worst-performing company in the world (http://www.alimenterre.org/en/breve/palm-oil-giant-wilmar-ranked-the-worst-company-in-the-world). Though recently, it has also been starting eco-friendly business practices due to pressures from environmental groups and NGOs (http://www.bloomberg.com/news/articles/2015-03-12/wilmar-chairman-pushes-palm-oil-industry-to-clean-up).

A local example would be Sinar Mas Forestry group managed by an Indonesian conglomerate family. Its driver of palm oil expansion is export to emerging and developed economies. There is a good report by Greenpeace on this matter: http://www.greenpeace.org/usa/wp-content/uploads/legacy/Global/usa/report/2009/3/sinar-mas-indonesian-palm-oi.pdf?887043.
