It is not misleading. Does tech industry only serve tech industry in terms of sales? When other companies fall, this impacts tech. Sales for teams, zoom, slack, m365 or google suite, data storage, infrastructure and application monitoring, various other software, payment apps, people management apps etc. Even if Amazon lays off in the warehouses, what does this tell you? Less money, so will likely be fewer corporate jobs too, as they often support other operations.
