Companies buy proxies not for bypassing but for work: monitoring competitor prices, checking ads in different regions, testing sites from different locations. This is standard practice.
Business proxies have different requirements: stability, dedicated addresses, an API for system integration. One department may need hundreds of addresses daily.
Legally, working with competitor data through proxies is a common analytics tool when platform rules and laws are respected.
For a company the key is a reliable provider with a live pool and support. A proxy failure means stopped analytics.
