Depending on the laptop (or with any laptop + smart plug) you can set charging thresholds, both for starting and stopping the charge (lower and upper limits), this way it will do a few cycles instead of staying fixed to a certain level of charge.

In order the worst things we can do to batteries are: leave them at 0% for years, leave them at 100% for years, leave them halfway for years (what happens when left plugged in with only an upper charge limit like 80%) - batteries need to do a few partial cycles at least, once in a while.

Well put, that’s the most commonly experienced anti-feature introduced, another less common one where they have been less and less lenient over the years is geolocation restrictions: people in the past could register with other countries (cheaper) pricing, today most legitimate customers cannot access their content even when traveling for a few days, or they risk getting blocked. Similarly to the region-codes on dvds and blurays, I can’t imagine it really helps sales, but it siloes consumers into country blocks and monopolies tend to like that.
