I only looked very briefly at one video.
1. No educational or entertainment value. Watching a time lapse of icing applied to a stacked cake is neither informative nor entertaining.
Understand that social media is now part of every business. As such, professional pastry chefs and cookbook authors have a presence on YouTube, Instagram, and/or TikTok. So the standard for content is pretty high.
Her work is beginner/intermediate home baker, so her audience will be the beginner baker.

Just an aside...a properly baked cake should not have a dry brown crust on it. And professional pastry chefs always torte their layers. There are a few rare exceptions, but those thick layers she is stacking into tiers is not something a professional does with cake.
The order in which a cake is judged is 1) how a cake tastes; 2) how it looks sliced and plated; 3) decorated on the cake stand. If the cake does not taste good, and it is not visually appealing on the plate to the guest, it doesn’t matter how beautiful that cake looked on the cake stand.
Baking at 325°F, using a non coated, light metal pan, and cloth baking strips will produce a soft crust and a level cake.
On what flavor the cake is, it should never have a dry brown crust on it.
