They want nice, predictable numbers, too - probably because whoever's spearheading this wants to keep their job. You still get scolded in the business world if you make exponentially more money than you originally forecast because it probably means you didn't really know what you were doing while committing company resources to the project. Almost all enterprise software doing anything with cash forecasting over a span greater than a few months will factor in inflation, and while we don't have great models for something largely arbitrary, we're talking about differences of a few tenths of a percent YoY vs 50-5000% variances YoY. Even over the past few months, even though we're saying bitcoin's super-stable, it's still super-volatile compared to almost any national currency.

The risk appetite for BTC-only businesses is concerning in itself. Holding large percentages of reserves in BTC is dangerous, especially for resource-strapped startups.... but most of those on the list have survived quite possibly the most boring (thinking purely as a speculator) valleys in BTC history, which was preceded by a drawn-out, moderate decline in value. Maybe they have low transaction volume and keep a tiny inventory (it's a hobby), or maybe they just have tons of resources in reserve to draw from, or maybe they really are just cashing out even though they don't accept fiat.
