I don't understand this. It's a free 7-day trial. If I cancel during the 7-day trial, the following cancellation terms apply: If you cancel within 14 days of your initial order, you'll be fully refunded.
7 Also, it's not even clear if the 7 days do even count towards the 14 days, since in that case they could just as well state "first 14 days are free". But they are not free, since they belong to the first subscription month. They'd be 14 consumed days of the first month if no cancellation is made.
This should mean that the 7 days are not a part of the initial order. The initial order would get placed automatically after 7 days, you are just expressing your intent to automatically order after the 7 days of trial.
If this is not true, then they are definitely scamming their users, but I doubt that they would risk going to court for this.
But what I definitely think is a big scam is the 50% cancellation fee of the initial order, with the condition that you only get to use the remaining days of the month.
For example, if you cancel in the third week, you still have to pay around USD 300 (the tweets indicated a USD 600 per year cost), but you only get one week for that, instead of being able to use the full 6 months (50% of a year) you are actually paying for.

If I go to that page, there is the following text (it's also in his Tweet):
Cancel before --> 26 Feb [today is 5 Feb] This means that they are actually giving you a cancellation right of 7+14 days, just as mentioned in the "subscription and cancellation terms" plus the 7 days.
According to Wolfram Alpha "today + (14 + 7) days" = Feb 26, 2022
So no, you are not getting scammed with this free trial.
