It’s either +44% (from $70) or -31% (from $101). Percentages are weird…

Yes, and it should probably be cheaper in Poland. But it’s really 17% more expensive in this case, not 44% (or 30% as the article calculates).

The Polish price includes 23% VAT, no?

15 years is too long, it doesn’t match the state of the industry or technological progress.

How is this too long? I would consider it a reasonable amount of time to receive security updates on a computer.

I have a notebook that I bought in 2012. It can run Ubuntu LTS 24.04, which is supported until 2034, without issue. There is no indication that the next release will stop supporting this hardware. I don’t see why Microsoft couldn’t provide this.
