Personally I see no problem in using on companies with more than 300 employees if ever the problem could be that of the license that you cannot use Defender for Business

Where is it stated that Microsoft 365 Defender is not recommended for big companies? I personally work on tenants of clients in the 1500-20000 user range with M365D. As I understand, Defender for Business is not meant for big companies, but M365D is. Defender for Business is the slimmed down SME version of Microsoft 365 Defender, hence the limitations. "Microsoft Defender for Business capabilities Microsoft Defender for Business is optimized to meet the needs of small and medium businesses of up to 300 users."
