My issue is with the way the sentence is phrased, making it sound as if the “arbitrary “ blocksize limit causes “bottlenecks” and “increases network costs”, not even a hat tip to the design decisions behind the current block size. Sure there is a mention further down, but leading with the FUD is the giveaway here IMO.

But I’m not surprised since they are shitcoiners that support the abomination that is BCH.

I'll never use this service, period.

If you make several purchases on purse you'll start to notice people taking your order, and then cancelling it later, sometimes after it would have already shipped if they fulfilled the order at the time they accepted it. In the mean time, had they not negligently accepted the order, someone else could have actually accepted and fulfilled it. This happened to me a few years ago, and likewise last year, so I know they haven't fixed the problem. And from the user stats of the people doing this, they're clearly doing it often and to a lot of people, while also fulfilling some orders. I don't know what kind of arbitrage game they're trying to play in the mean time from accepting an order and cancelling it, but it's extremely annoying when you're the person waiting to find out when your order ships, to instead find out the other person cancelled it and you have to start again.
