“Managing allele frequency”, genetic “Snapshot” and genetic “Freeze” indicate keeping the same allele ratio as the wild population. In the quote above you suggest ‘Preserving Genetic Diversity’ not “Frequency”. It does not preserve the allele ratio of the wild stock, but does in fact preserve the diversity.

No, we're maintaining
frequency. For example, if we have two phenotypes on the same allele, and in the wild population the phenotypes occur in equal ratios: 50:50. If we let a captive population change get that ratio to 50:1, it still has the same
diversity but the frequencies are vastly different from the wild population. And if we were to allow that to happen the captive population would be very different from the wild population. But if we maintained frequencies at 50:50, even if the wild population deviated to 51:49, the captive population would be fairly similar to the wild population. Much more than if we let the captive population get to 50:1.
I don't know where you're getting that snapshot or freeze are not
static. Those names inherently mean things do not change. And by that, we mean we do not want to change the frequency of alleles from the wild population
at time of collection.
