One is a proposal, which at the time, was mainstream enough to gain the support of a majority of California voters. (And, even today, although I don't think it would get a majority any more, it probably still would get a significant minority of California voters supporting it.)
The other is an extremely fringe view which has only ever been supported by a tiny percentage of the population.
I also don't think Eich was "out there advocating" for something. He made a private donation, which was not a significant amount in the grand scheme of things ($1,000 either way was not going to make any difference to the outcome). The law required that fact to be made publicly available, and then others publicised it; he didn't voluntarily choose to publicise his donation. When people publicly asked him about his beliefs on the topic, he avoided answering the question.
