Ehh, it's ok in the case of JetBrains - if your subscription lapses your license converts to a 'perpetual fallback license' so can just continue using the version you installed when the subscription was originally purchased.
I'm using a 4 year old version of PhpStorm with no issues and no subscription. My PyCharm sub ended 6 months ago and I'm staying on the 2023 version of PyCharm because the latest version comes with lots of AI which makes my CPU fans scream continuously.
Not quite. It's not the foreigners who pay the tariffs, it's the locals. The tariff is charged at customs when the product enters the country and the people paying that are the people doing the importing. Tariffs don't bring more money into the country, they just penalize local people who import goods from overseas. It's a tax. Back when Republicans were consistent they hated all taxes, heh.
From the point of view of the local consumer it makes no difference - the price rises unless there is a locally made substitute they can buy instead.
