Majority does not equal truth. There is a great diversity of churches under Protestantism, but we need to consider a few issues:

First, the majority of Protestant churches (PCUSA for instance) are apostate.

Also, not all Protestant churches believe in Sola Scriptura. Most apostate churches have rejected Sola Scripture, including the Church of Rome. So if we divided the churches that teach Sola Scriptura and those that don't - I think we will find the majority of apostate churches reject Sola Scriptura. And the diversity of these is much greater than those that do not.

And finally, if we consider just the Reformed Churches (not Arminian, who uphold the WCF and the five solas) and we look at the doctrinal diversity therein, while we do find there are many denominations, and some are quite small, yet there there is quite a bit more unity in basic doctrines of faith than found in just the one denomination called the Church of Rome.

So I think the diversity of beliefs being a product of sola scriptura is actually false. In truth, I think there is a more basic unity of doctrinal basics found within those churches that uphold sola scriptura. That the problem is not sola scripture, but the rejection of sola scriptura. Giving churches authority over Scripture has led to the fragmentation of the churches, and to apostasy in churches.
