The market htwo components: a large mass-market component in whimanis prisensitive, ana smaller performance-orientecomponent in whimanis muless prisensitive. SigmaSoft’s prois consireto technically superior. Eacompany cchoose one of two strategies:• Open architecture (Open): Mass market focus allowing other software venrs to velop procts for its platform.• Proprietary (Prop): Allow only its own software applications to run on its platform.penng upon the strategy eacompany selects, their profits woulbe:The Nash equilibrium for these companies is: A.proprietary for SigmaSoft anproprietary for ThetaTech. B.open architecture for SigmaSoft anproprietary for ThetaTech. C.proprietary for SigmaSoft anopen architecture for ThetaTech. is correct.In the Nash mol, eacompany consirs the other’s reaction in selecting its strategy. In equilibrium, neither company hincentive to change its strategy. ThetaTeis better off with open architecture regaress of whSigmaSoft cis. Given this choice, SigmaSoft is better off with a proprietary platform. Neither company will change its cision unilaterally.考点纳什均衡。如果 SigmaSoft 选择 Open 策略,，那么 ThetaTech选择 Open 策略可以获得更多的利润(600 300).如果 SigmaSoft 选择 Prop 策略，那么 ThetaTe选择Open策略可以获得更多的利润(700 400).所以对于 ThetaTe而言，它会选择 Open 策略。那么现在已确定 ThetaTe会选择 Open 策略，那么 SigmaSoft 选择Prop策略可以获得更多的利润(650 400). 为何不直接选两个都cheat也就是都是prop的情况呢？不是说Confess/confess就是Nash equilibrium吗？

请问是不是画成这个图
这个题为什么只用考虑S open/prop，然后就比较表格上方的左右两列。不用继续讨论T open/prop嘛？
请问这道题的情况是不是弱纳什均衡？
