i hate people who are just dogmatically opposed to double negatives in english. “not insignificant” is different than “significant”—admit of gradation or die
If you’re wanting to show your displeasure, don’t just tag staff or support. Take a page out of other consumer revolts and make sure your displeasure is known.
Don’t be an idiot. Do not threaten, harass or otherwise make this personal. Contact these companies, make your displeasure known, alert them that you are a customer and you will be leaving their brand across all boards unless they reverse their decision.
Be clear, be concise, be polite, but make your displeasure known.
