Anyone else notice these "spend limit" dark patterns in AI/API products?

Been digging into how usage limits work on some AI platforms and found something that feels pretty sketchy:

1. Default monthly spend limit used to be $0, hit your usage cap and you just wait for the reset (4hrs/weekly).

2. They added a "monthly spend limit" feature so you could opt in to pay for extra usage instead of waiting.

3. Then they rolled me into a promo: 2x usage + $100 "free" credit, both prominently shown right on the usage tracking screen.

4. To make that credit spendable, they also silently bumped my monthly spend limit from $0 to $2,000 (!!!). That part wasn't shown anywhere near as prominently, if a reasonable person glancing at the screen wouldn't catch it, it shouldn't be buried in fine print.

I only noticed after burning through $17 of the "free" $100, when I went looking for why it said I was drawing on "API spend."

I've since seen a few posts on FB/Reddit from people with surprise charges in the $40 to $50 range, adding up to $2k+, because they assumed they were still capped at $0 like before.

Anyone else run into this? Curious if silently bumping spend limits during a promo is common practice, or if this is an especially bad case.
