Jon Tennant, in a reposting of his comments on a disingenuous, Elsevier-penned Times Higher Ed piece:

When Elsevier uses words like ‘sustainable’, I do not think it means what it thinks they mean. The term ‘sustainable’ means maintaining Elsevier’s 37% profit margins and projected growth. Everyone else means not wasting hundreds of millions of dollars and more on a for-profit publisher that continues to aggressively mislead its customers, and lobby against progressive OA models, when a number of better, non-profit, community-led initiatives exist.

Tennant is—as he should be—merciless.
