It’s a shame these have become more commonplace.

Northern started issuing them instead of cardboard tickets a few years ago and other TOCs followed along after Network Rail/Cubic finished adding barcode readers to ~all ticket barriers.

I understand why: paper barcode-only tickets are significantly cheaper than cardboard tickets (their lack of a magstripe allows any generic thermal printer to be used), but their larger form factor makes them a definite UX downgrade.

I think this is less of a big deal in London because-- and the article entirely glosses over this prospect-- TfL accept contactless (e.g. contactless-enabled debit/credit cards, Apple Pay, Google Pay, Samsung Pay). This means anyone can land in London and immediately ride public transit using their existing bank card.

Considering that 100Mbit/s is 12.5MByte/s, the speeds you're seeing aren't horribly distant from your "up to" speed.

[For reference's sake, 8MByte/s is 64Mbit/s and 9MByte/s is 72Mbit/s

No. Creating the customer will charge the card $0.00 or $1.00 (depends on country/bank) and immediately refund the charge to verify the card itself, the CVC, the address, etc. In most cases, this tiny charge won't be noticed because of the refund.
