I thought the idea of getting donations instead of having ads was to avoid the theoretical possibility of altering the content. If indeed this is related to donor perception you might as well rely on ads, which are not certain to alter the content AND will make Wikimedia a financial powerhouse able to pursue multiple other projects.

Although I must confess that at this stage, the thought of Jimmy Wales commanding a billion dollar empire does not necessarily excite me.

Now, I am a self-professed idealist sometimes, but it strikes me that what would really be catastrophic would be an encyclopedia altering their content solely in response to a moral hysteria whipped up by a partisan media organization (regardless of their affiliation).
