The article does discuss the alternative of installing Linux. The reason it's not a good alternative is that businesses are unlikely to run Linux for day-to-day operations. While Linux may be a common topic of discussion in this online community, the majority of people affected by the increased Windows system requirements may not be familiar with Linux. I can also predict that by the time Apple decides to remove 1st generation silicon Macs from their OS support, there will likely be a Linux distribution that can run natively, such as Asahi. However, businesses using M1 Macs are unlikely to opt for Linux as an alternative; they will likely opt to purchase new computers instead.
