a program running on a 480 megahertz microcontroller can quite reasonably crash a million times a second; even a single 80-character error log line would be 80 megabytes per second or 7 terabytes per day. and it would be reasonable to record more telemetry from a crash than a single line
It is amazing how far we have come. On my own, I can only really screw up a few times per day, unless I am really trying. On a really, really bad day, maybe a few dozen times? How inefficient.
A washing machine is probably running a 48 MHz, not a 480 MHz processor, but even if it were running its core at 480 MHz, its network interface is probably not going to be able to output TCP packets at 1 MHz.
we are faced with the assertion that the washing machine was sending 3.7 gigabytes per day of data
someone asserted that that is an unreasonable amount of data for a washing machine to generate
i'm pointing out an easy way for a washing machine might generate 2000 times more data than that
the fact that the network interface is possibly insufficient to send the data out is irrelevant to the question of whether the washing machine can or cannot generate it in the first place, which is what was being discussed
however, i will point out that if it's using tcp, unless it opens a new tcp connection for each telemetry message, the tcp stack will batch together many telemetry messages into a single tcp segment, probably about 1500 bytes worth

of course you can control a washing machine with an 8051, or an eprom and a register clocked from the power line (see jeff laughton's printing press controller at https://laughtonelectronics.com/Arcana/One-bit%20computer/On...), or for that matter a mechanical timer or, as i've done, by unplugging the power cord and pulling a rubber drain plug when you think the agitator motor has been running for long enough. but more powerful control systems enable new functionality
historically it is true that manufacturers have used low-spec microcontrollers because more powerful ones were too expensive. today digi-key will sell you a 500-megahertz i.mx rt1010 cortex-m7 from philips/nxp, with 128 kilobytes and dc/dc conversion on-chip, for under four dollars, roughly π dollars in fact https://www.digikey.com/en/products/detail/nxp-usa-inc/MIMXR.... home appliances and motor control are two of the application areas the datasheet claims it's 'specifically useful' for. unlike an 8051, you can program it in micropython and single-step it over a debugging umbilical, and once it's deployed, it can send you surveillance data over the internet. and you can get cheaper and better chips on lcsc if you can read datasheets in chinese
oops, did i say surveillance data
i meant telemetry. telemetry, telemetry, telemetry
for better or worse this unlocks a lot of temptation for manufacturers to put ridiculously powerful cpus in things where they only serve to cause headaches to the consumer
other comments in this thread have even pointed out non-evil ways this could make manufacturers more profitable
